* Lens, bridge and temple measurements are in millimeters (mm); head width is measured in inches.
* Most frames are marked with sizing format: Lens Width-Bridge-Temple (example: 54-18-140).
* If you prefer a looser fit or have high cheekbones, choose one size up.
* Actual fit varies slightly based on frame shape, face shape and nose structure.
